Hardware Specifications and Architecture
1. Processor and Memory Configuration
Core Chip: Equipped with the Motorola MC68040 microprocessor running at a frequency of 25 MHz, it delivers high-efficiency instruction execution capability to meet the requirements of multi-task concurrent processing in industrial scenarios, such as running logic control, data acquisition, and communication protocol parsing simultaneously.
Memory Features: Built-in 8MB dynamic RAM (upgradeable to 16MB via a dedicated kit, corresponding to model PM511V16), integrated with an ECC error correction circuit. It can automatically detect and correct single-bit memory errors, preventing system malfunctions caused by abnormal memory data and ensuring stable program operation.
Memory Backup: Dependent on the system backup power supply and battery (e.g., SB522 battery module), it can maintain RAM data for at least 2 hours after power failure (2 hours in redundant configuration and 4 hours in single-module configuration). To extend the backup duration, the SB510 backup power unit (doubling the battery life) or the SB511 external battery interface (compatible with 24V/48V external batteries) can be added.
2. Interfaces and External Connections
The front panel of the module integrates a variety of dedicated interfaces to support hardware expansion and maintenance operations, including the following:
Program Card Interface: A dedicated PCMCIA slot designed for inserting system program cards (storing the basic program module QC07-BAS41 and optional modules). It is mandatory to keep the program card in place when the backup CPU in redundant configuration is booting up.
S100 I/O Bus Interface: Directly connects to the S100 I/O bus extension cable (maximum length: 12m), supporting single-bus or redundant-bus configurations to enable high-speed data exchange with I/O subracks.
Configuration and Maintenance Interface: Supports connection to configuration tools such as the Advant Station 140 for system configuration, program downloading, and fault diagnosis. It is also equipped with status indicator lights and a character display screen, which can display real-time CPU operating status, fault codes, and other information to facilitate on-site maintenance.
Mode Control Components: Includes a four-position rotary switch (for selecting CLEAR/STOP/AUTO/OFF LINE startup modes) and a reset button. It supports choosing different startup methods based on the duration of power failure; for example, the Auto mode enables automatic restart and recovery of pre-failure operating status after power restoration.
Redundancy Features and High-Availability Design
1. Redundancy Configuration Characteristics
The Advant Controller 450 supports the construction of a redundant hot standby system with dual PM511V08 modules, with the following core features:Hot Standby Mechanism: When the active master module is executing process control functions, the backup module stays in the hot standby state. It synchronizes the configuration data and operating status of the master module in real time via an automatic checkpoint mechanism, requiring no manual intervention.Fault Switchover: In the event that the master module detects a hardware fault (e.g., CPU abnormality, memory error), it will stop running immediately, and the backup module will seamlessly take over control tasks within 25 ms to achieve disturbance-free switchover, preventing process interruption. The switchover status will be fed back synchronously via module indicator lights and AdvaCommand system alarms.Configuration Requirements: The two PM511V modules in redundant configuration must have the same RAM capacity (either 8MB or 16MB for both), and program cards must be inserted into both the master and backup modules simultaneously to ensure that the backup module can load the complete system program during startup.
2. System-Level Reliability Assurance
Power Supply Redundancy Support: It can be paired with dual SR511 voltage regulators and dual mains power supplies to achieve power system redundancy. The regulators and power supply modules support hot swapping, allowing replacement without system shutdown and further improving system availability.I/O Redundancy Expansion: Redundant backup of I/O data transmission is realized through redundant S100 I/O buses (dual DSBC 174 bus expansion cards) or Advant Fieldbus 100 redundant buses, avoiding I/O communication interruption caused by a single bus fault.
